Question:
The ionisation of hydrochloric in water is given below:
HCl(aq) + H2O (l ) ⇌ H3O+(aq) + Cl–(aq)
Label two conjugate acid-base pairs in this ionisation.
Solution:
The two conjugate acid-base pairs in the ionisation of HCl are (HCl-Cl-) in which HCl is the conjugate acid and Cl- is the conjugate base similarly the second pair is (H2O-
H3O+) in which H2O is the conjugate base and H3O+ is the conjugate acid.
